JUMP-SEAT F OiR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 481,358, dated. August 23, 1892. Application filed April 23, 1892- Serial 110.430.32'7. (N0 model.)

To all whom it may concern: Be it known that I, GEORGE H. HUTTON, a

citizen of the United States, residing at Bal-' This inventionrelates to improvements in jump-seat vehicles, the main object being to provide an improved construction for extending the sides of the front seat when the latter is brought to position for use and contracting said sides when the seat is folded down under the back seat, whereby said front seat may be made narrow enough to fit between the vehicle sides and also wide enough to ao commodate two persons without crowding.

To this end the invention consists in the novel features of construction and combinations of parts hereinafter described.

The invention is illustrated in the accompanying drawings, in which Figure 1 shows a side elevation of the vehicle-body with single-seat adjustment. Fig. 2 shows a similar view with double-seat adjustment. Fig. 3 shows a section of the vehicle-body and front seatraised, with the back folded down. Fig. 4 shows a rear elevation of said front seat with the back turned up and a section view of the vehicle-body. In this View one of. the extension slide-arms is shown in section, as is also a portion of the seat. Fig. 5 shows atop view of the seat with the back removed. Fig. 6 shows a-perspective view of one of the locking-irons, slider arms, and connecting-rods.

The front seat A has at each end a crossplate B, provided with ears b, to which the upper ends of the standards or legs 0 pivot, and the lower ends pivot at d to the baseplate E on the carriage body frame. The seat-back F is supported by irons G, which have elbow or knuckle joints e to allow the back to turn forward and downward toward the seat, as shown in broken lines in Fig. 1. The jointed irons G have one end rigidly secured to the flat surface of the seat A and the other end to the back F.

An iron I has stop-lugs f and at each end an upturn g and an eye h, by which it is pivoted to a pin or bolt 11 on the cross-plate B, attached to the seat. The said pivoted iron I thus extendscrosswise below the seat A and crosswise of the legs 0. Said iron has position on the outer side of the legs and may swing by its pivot-eyes it toward and away from the seat-legs, so as to bear against the legsor hang off from them. When the pivoted iron I is against the legs, the stoplugs f will be in position to engage said legs,

and thereby sustain the seat in its elevated rod L, whereby on tilting the seat-back forward the lug-iron will swing outward away from the legs and disengage the stop-lugs f. The swing-iron I hasa lateral arm m, which projects at a right angle with respect to the pivots 2', and one end of the rod L is jointed to this arm, and the other end is jointed at n to the free part of the back iron G. By this construction and combination the seat-back F becomes the handle by which to cause the lug-iron I to swing on its pivot 2'. All these parts thus far described are well known.

The front seat has inclined sides M, each of which has a pair of supporting-arms N connected rigidly toit and fitted to slide on the upper side of the seat and connected thereto by screws 19, passing through slots 19 in the arms and fastening in the seat. Said sides may be moved outward and inward to widen or contract the seat, and this movement isobtained, in combination with that of the back and locking-irons, as follows:

Each iron I has a pair of prongs r at its two opposite ends, projecting upward beyond the pivots c' and extending approximately in the line on the upturns g, and thus at an angle to the lateral arm m. These prongs pass through slots 8 in the seat and engage loosely in openings tin the slide-arms N, which openings form sockets for the ends of said prongs. It will now be seen that upon raising up the back F, and thereby moving inward the irons I and locking the legs 0, the prongs r are at the same. time thrown outward, being on the opposite side ofthe pivots Land slide .outthe arms N, thus extending the sides M and widening the seat. Upon folding down said back and while the irons I move outward to release the legs the prongs r, are .moved .in-. ward and slide thearms N; thus drawing in the sides and contracting the seat to a width which will allow it to take position between' the vehicle sides. The cushion for the front seat comprises two pieces 0, connected by a bellows web 07. Sliding arms P are fastened-r to the middles of the sides M and.extend nearly to the middle of the seat, resting 'on the top of the same. Their inner ends are formedinto hooks a: to take over the binding of the'cushion-pieces, as shown-in-Fig: 1t .willbeseen that with this-constructionthe cushion-pieceswi-l-l always-be: held against the sides M, and the cushion will beextended andpontracted with--tl1eseat,= the -web0"-" forming--an textensible and collapsible bellows, connection-between themt The arms P will be-of suoha length that the cushionpieces will beheld tightly betweexr the hooks 0 and sides M. VWhen-the sidesare-extended;- it will be seen that'eachcushion-pieceisat forded threesupports-viaythe 1 two slidearms-N and the-middlearm P. e i I The cut-out spaces-R in the sides of the vehicle and the seatsides M have the sameshape,- and when the seat is folded down" the said seat sides just fill said cut-cut spaces, as seen provided with extensible sides;which are op-w erated by connection with swinging leg-lock 1 ing irons. I These irons have beenlocated on the inner sides of the, legs,- andewhen they swing inward toward each other they unlock The combination by which I secure the movement of the seat side's simultaneously with that of the locking-irons is much simpler. By locating the swinging irons on the outside of the legs and simply forming thereon prongs,

which loosely engage the slide-arms that supportthe scatsidesl obtain the desired movement. r

claim as new, and desire to secure by Letters Patent is. w 5 a 1. 1he combination of the seat, movable sides therefor k supported by sliding arms' N, which rest on theseat pivoted legs support= ing the seat, swinging irons Ikunder tlie'seat for locking'the said pivoted legs and located l on the outer sides of the'latter, said irons-pro vided with prongs r, projecting upward beyond the pivots of said swinging 'irons'and loosely engaging the slide arms which support the'seatsides; and "also having f lateral arms' m; a seat-back, jointed irons connecting said back with the seat, and rods connectin'g said jointed irons" and the lateral arms" of the swinging leg-locking ironsr -2.=A jump-seat for vehicles having extensible sides and extensiblecushions connected to said sidesw i 1 3.-The combination of the seat, extensible sides therefor supported by slide-arms resting on the seat, and anextensiblw cushion connected to said slide-arms. r-
